BRB-100 — Principle of operation

The BRB-100 is a security device which en-

sures the presence of ventilation, of heating

and/or of a sufficient air intake in case of fail-

ure of the main ventilation system. The back-

up box uses the same outputs as the ones

used by the regular ventilation system. It has

2 different and independent security modes:

The first security mode is used in case of an

extreme room temperature; the second secu-

rity mode is used in case of power failure of

the main controller or relay panel.

1. Extreme room temperature: Up to 6 fans

(or heaters) can be activated if the tempera-

ture in the room exceeds the temperature set

point of T1, T2 or T3 thermostats. When the

room temperature reaches the set point of a

thermostat, the respective output is enabled:

(T1 thermostat activates K1 output, T2=K2,

T3=K3). Each thermostat can enable 2 fans

or heating outputs.

If the backup thermostat is used to ensure ven-

tilation, its set point must be greater than the

start temperature of the last fan stage of the

ventilation control; if it is used for heating, the

thermostat’s set point must be lower than the

start temperature of the last heating stage of

the ventilation control.

You must adjust the temperature

set point of the thermostats on

a regular basis according to the

changes made to the temperature

set point of the main ventilation control. You

must also test your mechanical thermostats at

the beginning of each flock or more often.

2. Power loss of the ventilation controller or

relay panel: If the ventilation stops due to a

power lost of the main ventilation controller or

of the relay panel, the backup box activates K5

and K6 fans (or heaters) and asks for an open-

ing of the K4 curtains or vent doors.

Backup Loads: The backup loads must be

connected to a dedicated circuit breaker. Do

not wire the backup loads on the same break-

er as the relay panel.

The relay selection of this diagram is shown

for illustration purpose only. The actual relay

selection has to be determined in the field

and wired as shown.

*Using a Thermostat Controller: A con-

troller can be used to replace mechanical

thermostats. Using this type of controller

changes the power supply connection of the

BRB-100. It also changes the way actuators

and thermostat terminals are connected. If a

thermostat controller is used, refer its wiring

diagram to make the connections.

Installation Notes: Leave a clear-

ance of at least 12” to the left

of the controller’s box and 16”

to the left of the relay panel to

allow covers to be removed for

maintenance.
